Dear AH, I saw some re-enactors recently who talked about how during the American Civil War, the surgeon general kept statistics as to the rate at which different weapons caused wounds, with only 1/147 wounds looked at coming from bayonets, less than 1%.
They also mentioned, however, an officer looked at the stats in the 1870's (possibly 1880's, I don't remember exactly) and found that if you add in stabbing wounds of unknown origin, it goes from <1% to ~10%, meaning that bayonets were either an almost negligible proportion of casualties, or a substantial minority, depending on how you looked at the stats.
Is there a consensus among modern historians on how to interpret these numbers?
Could it be that there is a distinction between 'wounded' and 'dead'? The surgeon would see the ones that are still living.
I think a more interesting question to first ask is:
What was the tactical purpose of a bayonet?
I feel like the answer to that question would shed some light on your own question, so perhaps someone qualified can give an answer.
